forward motion of t sembled and as conveniently disconnected at anytimefor repairs and the substitution of new \parts. Formed upon the flange23 at regular intervals is a series of apertured lugs or ears 29, for apurpose hereinafter described. It will be observed that the arm 14 ofthe lever 10 extends across the outer surface of the shell and isadapted when adjusted to throw the clutch collar 8.out of connectionwith the clutch collar 4 to lie in the path of the said lugs 29.

Assuming that the gear 5 is driven in any suitable manner from the motoror rinnA driving element, and constitutes with' the gear 2 the drivinggear or element of the gearing, it will be understood that when saidears are locked to the shaft by the clutch evices, the gears 2 and 3will be fixed with relation to each other, and hence that all the gearsof the gearing will be locked to each other and to the shaft 1 totransmit motion in a forward direction to said shaft. When the clutchelements 4 and 8 are in engagement, the arm 14 of the lever 10 lies outof the path of movement of the lugs 29, thus allowing the shell, whichis then a fixed part of the gearing, to have free and l'unobstructedmovement. When it is desired to reverse the gearing for the pu ose ofrcversing the direction of rotation o the shaft, the rod 15 is operatedto throw the arm 14 of t-lie bell crank lever into the path of movementof the lugs 29v of the shell, whereby in such movement the arm 12 of thelever will swing outward, carr ing with it the clutch member8 which wibe drawn out of engagement with the clutch member 4, thus unlocking thedrive gear from the shaft. Motion ot the transmission or dierential gearwill then be prevented" by engagement.

of one of the lugs 29 with the lever arm 14, and hence as'the drivinggear continues to rotate forward the spindles 25, will be rotated ontheir axes and therebyitransrnit reverse motion to the driven gear 2 andshaft 1, which will accordingly be rotated rear wardly without changingthe continuous ie driving element.

` When the controlling lever is swung in the opposite direction, themovement of the arm 14 out of the path of the engaged lug 29 will freethe transmission gear as a whole for rotary movement with the shaft,while the arm 12 of the lever will oe swung inward to bring the clutchmembers into engagement, whereby all the gears will again be lockedtogether to rotate. the same in a forward direction.

It will thus be seen that the gearing constructed and applied asdescribed may be ar.- rangod to rotate the driven clement forwardlythrough n. corresponding motion ol' tho driving element and to reversethe direction of motion of the driven element without '1 reversing 'thedirection of inf-tion of the drivotlier part coupled to the gear 5,which, in

this event, will constitute, with the gear 2, the driven element. Theoperation in this mode of use ol' the gearing in seeming :i reversal ofmotion of the driven clement withoutv reversing thel direction ol'motion ol' the' 75 driving element will be apparent.

'hile the controlling lever is designed to simultaneously couple thegear 2 lo the shfil't and lock the differential gear :is a wholelagainst rotation bodily with the shaft, and

for simultaneously freeing said differential gear and locking thedriving gear to the shaft., it will be understood that different meansmay be employed in conjunction with the lever for this purposethat is tosay, that instead of employing the lugs 29 to engage the arm 14 of thelever, any suitable means, such as a band brake or other equivalentdevice, directly or indirectly operated or rontrolled by the lever maybe employed to control the differential gear in the manner described. InFigs. 2%, 4 and 5 I have shown a band-brake mechanism for this.purposely This brake mechanism comprises a pair ot friction bands 31engaging the periphery 'of 95 the shell on opposite sides of the flange23, each band being pivotally connected at one end with one of the armsol' a bell-crank lever 32 fulcrumed on a suitable pivot bolt, rod orstud 33. On a post 34 is fulcruined the bell 100 crank lever 10 which ispivoted at the angle of intersection of its arms 11 and 12 on a pivotscrew 11a carried by said post. The arm 12 is constructed and connectedwith thc sliding scribed with reference to Figs. 1 and 2. The oppositeends of the brake bands are pivota ly connected with the other arm ofthe bellcrank lever 32 from which extends a rod 35,

clutch collar in the manner shown and dewhich is fastened to the rod 15by a clip or No coupling 36. It will be apparent from this constructionthat when the rod 15 is moved in one direction the clutch collar 4 willbe rctracted and the brake applied to lock the shell from movement, thusreversing the dircction of movement of the shaft without reversing thedirection of movement of thc drive gear. On the other hand when the rod15 is moved in the opposite direction the clutch collar will beprojected to lock the 1 20 drive gearto the shaft and the brake will bevloosened to free the shell, thus causing all the parts of the gearingto be locked from independent movement, so that they will turn forwardlywith the drive gear and shaft.
